introduction： An instrument for measuring heat flow in heat production and heat consumption systems。The heat score is a hot water calorimeter﹑Steam calorimeter﹑Superheated steam calorimeter and saturated steam calorimeter。Hot water calorimeter is used to measure the heat flow of hot water boiler or heat supply network。thermodynamically﹐Heat flow is equal to water flow and water supply﹑Product of enthalpy difference of return water﹐The enthalpy difference can be replaced by the product of the average specific heat and its temperature difference﹐So we put a flow transmitter and two thermal resistors in the pipe﹐The measured flow and temperature signals are sent to the calorimeter﹐
